What+is+the+fourth+dimension

Hey everyone, I was doing some reseach on the fourth dimension to see what its all about, so heres some research and pictures that I found. If anyone finds anything useful I was thinking we could post some information on here. I know we are still in the brainstorming stage, but on friday we all seemed pretty interested in this topic, so here is what i found:

The fourth dimension  is generally understood to refer to a hypothetical  fourth  spatial  dimension , added on to our normal three dimensions. It should not be confused with the view of space-time, which adds a fourth dimension  of time to the universe. The space in which a fourth dimension  exists is referred to as //4-dimensional Euclidean space//. Beginning in the early part of the 19th century, people began to consider the possibilities of a fourth dimension  of space. Mobius, for example, understood that in a fourth dimension , a three  dimension  object could be taken and rotated on to its mirror image. The most common form of this, the four dimensional cube or tesseract, is generally used as a visual representation of a fourth dimension. Later in the century, Riemann set out the foundations for true four-dimensional geometry, which later [|mathematicians] would build on.

In our three dimensional world, we can look at all space as existing on three dimensions. All things can move along three different axes: altitude, latitude, and longitude. Altitude would cover the up and down movements, latitude the north and south or forward and backward movements, and longitude the east and west or left and right movements. Each pair of directions is at a right angle to each other, and therefore is referred to as mutually orthogonal. In the fourth dimension , these same three axes continue to exist. Added to them, however, is another axis entirely. While the three common axes are generally referred to as the x, y, and z axes, the fourth dimens    ion  falls on the w axis. The directions that objects move along in the fourth dimension  are generally called ana and kata. These terms were coined by Charles Hinton, a British mathematician and sci-fi author, who was particularly interested in the fourth dimension. He also coined the term tesseract to describe the four dimensional cube.

Here is a picture of a tesseract **8-cell** or **regular octachoron** or **cubic prism**, is the [|four-dimensional] analog of the [|cube]. The tesseract is to the cube as the cube is to the[|square]. Just as the surface of the cube consists of 6 square [|faces], the hypersurface of the tesseract consists of 8 cubical [|cells]. The tesseract is one of the six [|convex regular 4-polytopes].
